Robot in the City

I have been working on this science fiction drawing for about a month long. It was tough with the buildings with all of those windows and trying to make them look straight as possible with no ruler or anything to draw perfect lines with. This work is done with color pencils on a red color paper. It's also a challenge to make the robot look metallic and shiny as best that I can make. The eyes were tough to somehow make them glow behind the dark black eye screen. The yellow van parked behind the robot seems a little flat, but I wanted to make it fade away and less important than the robot. So are the buildings behind the van. The clouds are even very faint in the sky. This helps make the robot stand out more and shows the distance as well. Enjoy the image and you can click on it to enlarge it.
